## CAD (KiCad official)

- Symbol: `MOC3022`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `moc3022-etched.step` / `moc3022-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `moc3022.step` / `moc3022.glb` are the bare package body.
